INTRODUCTION
This is the transcription of the Apollo ll flightcrew communi-
cations as recorded on the command module (CM) data storage equipment
(DSE), and subsequently transmitted (dumped) to Manned Space Flight
Network stations. Magnetic tapes containing dumped voice and onboard-
recorded ground elapsed time (GET) were forwarded to the NASA Manned
Spacecraft Center, Houston, Texas. Transcription of these tapes was
mauaged by David M. Goldenbaum, Test Division, Apollo Spacecraft Pro-
gram Office, to whom questions regarding this document should be
referred.
The Apollo ll mission was flown July 16 to July 24, 1969.
Communicators in the text are identified as follows:
Command module:
CDR Commander Nell A. Armstrong
(_P Command module pilot Michael Collins
r LMP Lunar module pilot Edwin E. Aldrin, Jr.
SC Unidentifiable crewmember
MS Multiple speakers (simultaneous)
Mission Control Center:
CC Capsule communicator (CAP COMM)
In the text, a series of three dots (...) is used to designate
those portions of the comm_mications which could not be transcribed
because of garbling. One dash (-) is used to indicate a speaker's
pause or a self-interruption. Two dashes (- -) are used to indicate
an interruption by another speaker or a point at which a recording
was abruptly terminated.
